An energetic monster, his early talk spots with kids in Season 36, often discussed the importance of exercise and healthy habits with young visitors.

Although unnamed, the character was referred to on the set as "FilFil," as his design is based on that of Filfil from Alam Simsim. Beginning in Season 38, he gained an identity as Murray, hosting the "What's the Word on the Street?" segments that precede each episode of Sesame Street. In season 39, he began appearing in his own segment, Murray Has a Little Lamb, where he goes to a certain school with his pet lamb, Ovejita. In season 40, he started serving as a host of the new "block format", presenting the letter and number of the day, introducing upcoming sketches within the episodes, and announcing the sponsors. Murray was given a new segment in Season 42, Murray's Science Experiments, which are spread through the tune-ins. He is again with Ovejita.

I kinda keep Murray like, who's the guy on Fraggle Rock? Uncle Traveling Matt. Because I feel like he goes out into the real world, and when we put him onto the street, there's just a million characters who can service this. [1]
